8 Claims.

The present invention relates to improvements in dispensing containers and more particularly that type in which a flexible bag, the contents of Which is to be dispensed, is enclosed in and more 5 or less supported by a rigid housing or shell.

An object of the present invention is the provision of novel means for severing or rupturing the bag in a predetermined zone preparatory to initial dispensing of the contents. To this end 10 the invention includes a toothed cutting device which normally occupies a retracted position within a neck that forms a part of the housing or shell and through which the contents are dispensed, such cutter being capable of projec- 15 tion through the housing at the will of the user.

A further object of the invention is the provision of a follower or movable bottom for the housing or shell which is employed in forcing the bag into engagement with the cutter, said showing the bag partially collapsed and the side walls folded and occupying the space provided in the follower for accommodating the folded wall.

Fig. 3 is a horizontal sectional view taken sub- "stantially along the line 33 of Fig. 1.

Fig. 4 is a sectional view taken substantially along the line 4-4 of Fig. 2.

Fig. 5 is a fragmentary sectional view taken along the line 5-5 of Fig. 4 with the nozzle rotated to another position.

By reference to the accompanying drawing it will be observed that the flexible bag III which may well be formed of pliofilm or like material is encased in a housing II or shell including a circular body I2, the lower end of which is closed by a movable follower l3 or bottom, while its upper end is permanently closed by a dome- 50 like wall M.

The movable follower l3 or bottom is held in place by an internal hem IS on the body and preferably is hollow as shown. The upper wall I6 is dome shaped and of somewhat less diameter than the body l2 of the housing and so follower also being formed to accommodate the' positioned with respect to the remainder of the follower that together with adjacent portions of the body 2, it provides an annular upwardly facing recess I! or channel designed toaccommodate the folded wall of that portion of the bag 5 .from which the contents have been removed.

-The dimensions of the follower |2 are such that it operates smoothly within the body l2 and may be shifted lengthwise thereof toward the end wall [4 in dispensing the contents of the bag 10.

The upper end wall I4 is formed with a central opening l8 to the walls of which a circular neck I 9 is rigidly attached by a seam 20. A dispensing nozzle and cutter unit 2| snugly fits into the neck l9, Both the neck l9 and the cutter and nozzle unit are intended to be enclosed by a skirted cap 22 which is held in place by frictional engagement with corrugations 23 formed near the upper end of said nozzle and cutter unit.

The cutter and nozzle unit 2| is movable between two extreme positions in one of which the cutting teeth 24 are retracted to an inoperative position within the neck l9, while in the other position the teeth are projected substantially as 25 shown in Figs. 2 and 4. This unit consists of a circular sleeve 25, .the lower end of which is provided with an annular series of teeth 24, while the upper end is tapered inwardly to form a nozzle 26 including a central discharge opening 27. The annular series of corrugations 23 which, as will be apparent presently, facilitates gripping of this unit 2| for the purpose of rotating the cutter and moving the latter between operative and inoperative positions. The cutter and nozzle unit 2| is releasably held in either of these positions by detents 29 which project inwardly from the neck l9 into engagement with the upper or lower annular grooves or channels 30 and 3| respectively of said sleeve 25. These grooves or channels are provided externally of the cutter and nozzle unit and communicate with each other by way of vertical grooves 32 which correspond in number to that of the detents 29.

In operating this cutter and nozzle for the purpose of rupturing the bag I0, preparatory to dispensing the contents thereof, the cap 22 is removed and the nozzle and cutter unit 2| is rotated to bring the vertical grooves 32 and detents 29 into register with each other. This unit is then moved downwardly and the follower I3 is manually moved upwardly towards the dispensing end of the container. Thereupon and while continuing to apply pressure to the follower l3, the cutter and nozzle unit 2| is rotated. This, as is obvious, ruptures the bag In and permits thedischarge of the contents through the nozzle opening 21.

Modifications may be resorted to within the spirit and scope of the appended claims.

I claim: a

1. A container comprising a rupturable fiexible bag, a rigid housing therefore including a body, a bottom movably positioned in one end of the body, an end wall closing the other end of the body and having a neck defining adischarge opening, a cutter and nozzle unit in said neck, means whereby said unit may be moved thereby to operatively position the cutter, and a closure forsaid opening.

2. A container comprising a rupturable flexible bag, a rigid housing therefor including a body, a bottom movably positioned in one end of the body, an end wall closing the other end of the body and having a neck defining a discharge opening, a cutter and nozzle unit in said neck,

means whereby said unit may be moved thereby to operatively position the cutter, and-a closure for said opening, said bottom including a raised central portion for engagement with the bag and an annular channel surrounding the raised portion to accommodate portions of the bag from which the contents have been dispensed.

3. A container comprising a rupturable flexible bag, a rigid housing therefor including a body, a bottommovably positioned in one end of the body, an end wall closing the other end of the body and having a neck defining a discharge opening, a cutter and nozzle unit in said neck, means whereby said unit may be moved thereby to operatively position the cutter, and a' closure for said opening, said cutter and nozzle unit including a sleeve fitted into the neck, cutting means provided at the inner end of the sleeve, and means whereby the sleeve may be positively held in position to retract or project said cutting means.

4. A container comprising a rupturable fiexible bag, a rigid housing therefor including a body, a bottom movably positioned in one end of the body, an end wall closing the other end of the body and having a neck defining a discharge opening, a cutter and nozzle unit in said neck,-means whereby said unit may be moved thereby to operatively position thecutter, and a closure for said opening, said cutter and nozzle unit including a sleeve fitted into the neck, said sleeve having relatively shallow external grooves spaced apart lengthwise thereof, and detents on the inner face of the neck for engaging the grooves one at a time and thereby securing the cutting means alternately in operative and inoperative positions.

5. A container comprising a rupturable fiexible bag, a rigid housing therefor including a body, a bottom movably positioned in one end bf the body, an end wall closing the other end of the body and having a neck defining a discharge opening, a cutter and nozzle unit in said neck,
